Technological possibility and reality don't always meet, and that is my point. Nobody has suggested that f/2.8 lenses are not possible for E-mount, but the fact is, Sony is clearly favoring f/4 to keep size and weight down, which bodes well with a key selling point of the E-mount. The opposite is true for A-mount (a reason SLTs grew in size substantially, from A33/A55 to A65/A77).

Yes, but for anyone that doesn't mind the size, they can simply use their 2.8 A-mount lens on the E-mount camera, with an adapter. Thus, they don't need an A-mount camera to be able to use an A-mount lens.

So you actually believe that Sony would make A-mount lenses because it takes more resources to do so than would A-mount bodies which can share most parts with E-mount (except for the mount and firmware differences)?
